LEVELSTATE 202 3227 Float Level Switch

Overview

LEVELSTATE 202 3227 is a magnetic float operated level switch for liquid point level detection. LEVELSTATE 202 3227 uses a buoyant float with embedded permanent magnet to actuate a sealed reed switch inside the stem, providing discrete switch signal for high level alarm, low level alarm, pump start stop and tank overflow protection. This LEVELSTATE 202 3227 is widely stocked as spare liquid level sensing unit for water and chemical process automation assemblies.

Features

LEVELSTATE 202 float level switch is a single point level sensor with compact threaded process connection. The reed switch is fully hermetically sealed, free from contact oxidation and liquid corrosion. The switch action can be configured as normally open or normally closed according to installation direction. LEVELSTATE 202 3227 is available in stainless steel wetted construction with optional sealing material for clean water, weak acid and weak alkaline liquid. It has no power requirement for the contact element, simple wiring and long service life. It can be mounted vertically from tank top or horizontally on tank side wall. This unit has robust mechanical structure, resistant to vibration and liquid flow impact. It complies with industrial EMC requirements, designed for 24/7 continuous operation in water treatment, cooling water tank, chemical storage vessel and wastewater monitoring cabinets. The code 3227 represents the production serial number of this unit.

Specifications

LEVELSTATE 202 Magnetic Float Level Switch Brand: LEVELSTATE Model: 202 Serial No.: 3227 Type: magnetic reed float level switch Sensing principle: float magnet actuates reed switch Contact type: SPDT reed contact Contact rating: standard low voltage low current rating Wetted material: SUS304 Seal: NBR or FKM optional Process connection: standard thread Mounting: top vertical or side horizontal Protection class: IP65 Ambient temperature: -10℃ ~ +60℃ Liquid temperature range: 0℃ ~ 80℃ Status: classic LEVELSTATE level switch spare

Principle

LEVELSTATE 202 3227 floats up and down following liquid surface. This Float Level Switch carries permanent magnet inside the float. When liquid level reaches the set point, the magnetic field triggers the internal reed switch to change contact state. The switch signal is sent to PLC, relay or alarm panel to execute interlock or alarm function. The sealed reed switch isolates the electrical contact from the liquid medium.

Applications

LEVELSTATE 202 is deployed in water supply tanks, cooling water circulation tanks, chemical liquid storage vessels, wastewater sump and industrial liquid buffer tanks. It monitors high and low liquid level for pump protection and overflow prevention. LEVELSTATE 202 3227 is stocked as spare float level switch for liquid level monitoring automation assemblies.
